Water itself is an example of a homogeneous mixture. It often contains dissolved minerals and gases, but these are dissolved throughout the water. Tap water and rain water are both homogeneous, even though they may have different levels of dissolved minerals and gases.
In the human body, blood plasma is an example of a homogeneous mixture. This is a colorless fluid that holds the blood cells in suspension. It makes up a little more than half of the volume of human blood.
A bowl of Fruit Loops cereal is a heterogeneous mixture because it has cereal bits of many colors floating around in milk.
Smog is a heterogeneous mixture of various particles suspended in the air.
